1 Claim.

The invention relates to a folding chair which is highly simple both foruse as well as manufacture.

An object of the invention is to provide a chair which will oifer a softseating means;

Another object of the invention resides in constructing a chair providedwith a back which can be adjusted to the body of the person using thechair;

Still another object of the invention resides in constructing a chairwith the smallest possible quantity of material; making it thus verylight; enabling it to be manufactured rapidly and simply; reducing thusthe cost of manufacture; avoiding complication and inconvenience duringfolding and unfolding; giving to the chair a new, attractive appearanceand finally disposing the elements thereof in such a way that the foldedchair may be reduced to a minimum of volume.

For better comprehension of the invention and in order to enable one toreadily practice the same, a drawing of an illustrative embodiment isadded wherein:

Fig. 1 is a perspective view of a chair embodying the present inventionand seen laterally from behind in position of use;

Fig. 2 is a side elevational view, also in position of use;

Fig. 3 is a front elevational view of the chair in folded position,reduced to the smallest volume thereof.

In the various figures of the drawing the same reference numbersindicate the same or corresponding parts.

In conformity with the purpose stated above, for manufacturing eachchair it will be sufficient to use only six prismatic laths ofrectangular cross-section, five cylindrical sticks for connecting thesix laths, and providing the frame formed by the cylindrical sticks andlaths at suitable sites with three canvas sheets of quadrilateral shape.Nothing else.

The six laths are used in three pairs. A first pair la and lb form thetwo fore jamb posts I which are each provided with a central hole 2 andwith a second hole 3 near one end thereof. The second pair 4a and 4bform the two hind jamb posts l which are each provided with a first holeat the same height as hole 2 ofeach fore jamb post i, and with a secondhole 5 again at the same height as hole 3 of jamb post I, and finallywith a third hole 6 near the end of said hind jamb post l which isadjacent to the previously mentioned hole 5. The third pair of laths 1aand lb are each provided with a hole 8 near 2 one end of each lath and asecond hole separated from the hole 8 by the distance between the holes5 and 6 and arranged to coincide with hole 5 when the parts areassembled in the manner hereinafter described.

The connection of these three pairs of jamb posts l, 4 and l is effectedby means of five cylin drical sticks which all have a uniform diameterwhich is greater than holes 2, 3, 5, 6 and 8. At each end of each sticka portion reduced in diamter is formed so as to enable fitting it intothe corresponding hole. Thus stick 9 forms the connecting means betweenjamb posts la and 4a of one side and the corresponding jamb posts lb and4b of the opposed side. The ends of stick 9 are not glued so as toenable jamb posts I and t to effect a rotatory movement round eachfitted end of stick 9. Another stick [0 will form the connecting meansbetween the perforated ends of the two fore jamb posts la and lb. Asthis stick l0 will remain seated fixedly within holes 3, it may be gluedto the parts la and lb so as to give to the construction greaterrigidity during use. A third stick ll forms a connecting means betweenthe perforated ends of the two hind jamb posts 411 and 4b and as alsothis stick I I will remain fixedly within holes 6, it also may be gluedso as to strengthen the construction against wear and tear. A fourthstick l2 forms a second union between the two hind jamb posts 4a and 4bat a location below stick ll and it will unite at the same time the twoupper jamb posts la and lb by extending through the holes which havebeen made for this purpose in jamb posts 4a and 4b as well as in jambposts la and lb. Stick l2 may be glued into jamb posts 4a and 4b, butnot into jamb posts la and lb which are arranged on the outside, thusenabling jamb posts la. and lb to effect a rotatory movement round thetenon of said stick l2. Finally a fifth stick l3 will form theconnecting means between the perforated extremes of the two upper jambposts la and lb. This stick l3 again may be glued, as it will remainseated fixedly within holes 8.

The chair is completed by the addition of three canvas sheets to theframe described above. One sheet l4 will be stretched or spannedadequately, for example by doubling the extreme of the sheet round thecorresponding stick and sewing it together so as to retain it around thelatter, between stick lll and stick l2, thereby forming the seat of thechair. A second canvas sheet l5 will be stretched in the same fashionbetween the two non-perforated extremes of the upper jamb posts 3 7a and11), thereby serving as a back rest to sustain or support the body ofthe person seated upon the chair. A third canvas sheet l6 extendsbetween sticks H and I3, and is secured to the two sticks II and [3 inthe same way as the canvas sheet [4 is secured to the sticks l0 and I2.This third canvas sheet IE will strengthen or support the backlpart ofthe chair, particularly when the user of the chair inclines the backpart of the chair toward the rear, as indicated by arrow IT in Figures 1and 2, placing the chair;

thus in a position of comfortable repose for the user.

During use, the folding chair. which forms ,the.

subject-matter of this invention,willoccupytheunfolded position shown inFigures land 21011 even a position wherein the pair of upper jamb posts(a and lb is still more inclinedtow-ards'the rear if it is wished torepose comfortablyupon the chair, but when the chair is not in use, itis pos- I sible to foldhit into a minimumvolume and keeping it thusfoldedatanyisuitableplace Of'jStOI- age.,. Forfolding the chair, it isonlynecessary to push stick illtowards stickl2'so as to bring jamb posts4 upon jarnb postal; Forreducing the length of the folded chair; theupper jamb posts-lmay be turned; in the; direction of arrow l8around thetenonsseatedwithin hole fisothat the parts ofijamb posts Ia and 1b whichcarry canvas sheet [5,- will move around 5 and will thenoccupy'theinverted position seen in Figure 3, thus reducing the chairto;a really small volume.
